IMPORTANT
Installer and Users please note:
These instructions should be read carefully and left with
the user of the product for future reference.
Installation
T
he NJA1000 must be installed by a competent electrician in
accordance with the current IEE wiring regulations.
Connect the NJA1000 to the mains supply (nominally 230V AC).
The NJA1000 must be earthed. NEVER disconnect the earth, even in
an attempt to prevent ‘hum’. If the earth were disconnected, it could
result in equipment connected to the input (even indirectly through a
mixer), such as microphones, becoming live in the event of a fault
(such as a liquid spillage into the amplifier).
If the mains lead is damaged, it must be replaced by the
manufacturer or an authorised service centre.
If the mains plug needs to be replaced, proceed
as follows:
•
Connect the brown wire to the terminal labelled
"L".
•
Connect the blue wire to the terminal labelled
"N".
•
Connect the green/yellow wire to the terminal
labelled with the earth symbol or "E".
•
Make sure that the cord-grip is positioned correctly (over the outer
sheath of the cable) and is fully tightened.

Install the NJA1000 away from sources of moisture; avoid areas
where drinks can be spilled onto the amplifier as this may cause
serious damage.
The NJA1000 requires a "line level" signal. This is the signal level
from a mixer, a CD or tape player, or the audio output from a video
player or satellite TV receiver. This signal level is generally referred
to as +4 dBm or 1.22 V. A signal from a microphone, electric guitar
or turntable is not suitable; neither is the speaker output from
another power amplifier, which may cause damage to the NJA1000
if connected to an input. A signal of 1.22 V RMS (+4 dBm) is required
to achieve full power output with the volume controls set on
maximum.
